i am using this script since years to have running one build/update-server
caching all packages in a local-repo and all other machines in the network
have only the via http exported cache-repo active

this machine must have all packages used in the whole network installed
this si for fedora, but CentOS should not be the big difference

1. you save bandwith / time
2. you can be sure that all machines having the same package-versions

[root at buildserver:~]$ cat /buildserver/repo-cache.sh
#!/bin/bash
basearch=`uname -i`
releasever=`rpm -q --qf "%{version}\n" fedora-release`
# Alle Subfolder unter "/var/cache/yum" durchlaufen und RPM-Pakete
# in das eigene Repo kopieren
for g in `ls -1b /var/cache/yum`
do
 if [ -d /var/cache/yum/$g/packages ]
 then
  echo "/var/cache/yum/$g/packages/ > /repo/cache/fc$releasever/"
  sudo cp --verbose /var/cache/yum/$g/packages/*.rpm /repo/cache/fc$releasever/ 2> /dev/null
 fi
done
sudo createrepo -d /repo/cache/fc$releasever/
sudo chown -R builduser:builduser /repo/cache/fc$releasever/
sudo chmod -R 755 /repo/cache/fc$releasever/
